Hydroperfluoroalkanes are well known as being rather inert chemically.Hydroperfluoroalkanes react at high temperature with carbon tetrabromide and carbon tetrachloride to yield bromoperfluoroalkanes and chloroperfluoroalkanes. - Keywords: Hydroperfluoroalkanes; High-temperature reaction; Carbon tetrabromide; Carbon tetrachloride; Bromoperfluoroalkanes; Chloroperfluoroalkanes

- PYROLYTIC REACTIONS OF PERFLUORINATED CARBOXYLIC ACID HALIDES
-
Unlike other acyl halides, perfluoroacyl fluorides only enter into reaction with polar reagents.Perfluoroacyl fluorides, perfluoroacyl bromides, and perfluoroacyl iodides are smoothly decarbonylated at active carbon at elevated temperatures.In the absence of the active carbon the perfluoroacyl fluorides react with halogens, polyhalogenoalkanes, and iodoperfluoroalkanes with the formation of the corresponding halogenoperfluoroalkanes or their mixtures with perfluoroacyl halides; the low yields of the iodoperfluoroalkanes in the reaction of perfluoroacyl fluorides withiodine are explained by their ability to act themselves as reagents in these processes.The catalytic properties of active carbon are due to its ability to transfer electrons to the molecules of the adsorbed reagent and to hold the reaction particles on the surface; graphite and nickel also have specific catalytic activity.
